Despite the success of Avengers: Endgame, which is currently the second highest grossing film in history with a good chance to top the list, some fans were sad to see some of their favorite heroes leave — especially Jeremy Renner. The Hawkeye actor had to say goodbye to his longtime screen partner Scarlett Johansson, whose character Black Widow sacrificed herself in the Marvel Studios film.

"We weren't fully aware of [the Black Widow movie], but, even when that became clearer that it was one of the things that they were intending to do, no one told us not to do what we were doing," Markus explained.

"Right, and that's function of her arc, right?" McFeely added. "Her finally finding a purpose, a family, and being willing to sacrifice everything for that family. I think of her as perhaps the strongest person in the whole movie. She's the woman on the wall in the five years. And even when Captain America has doubts, and remember he says to her, 'Maybe we don't need to be doing this.' She does not share that opinion."
